Injury incidence rate, severity and diagnosis in male volleyball players

Prevalence of lower limb pain and disability in football, hockey, and floorball players

BACKGROUND

Currently there are not enough studies that compared frequent types of collective sports with regard to the prevalence of pain and disability of the lower limb.

OBJECTIVE

To determine the prevalence of lower limb pain and disability in team sports players.

METHODS

388 athletes with average age 27.26 ± 4.69, from sports clubs at the national level were included in the study. The Oxford Hip Score was used to determine the prevalence of hip pain. The International Knee Documentation Committee was used to determine the prevalence of knee pain. The Foot and Ankle Disability Index was used to determine the prevalence of ankle pain.

RESULTS

Hockey players had a prevalence of hip pain of 97.2% and a 14.3 times higher risk of developing hip pain compared with football and floorball players. Floorball players had a 81.9% prevalence of knee pain, with a 3.8 times higher the risk of knee pain compared with football and hockey. Floorball players had a 62.3% prevalence of ankle pain and a 1.8 times higher the risk of developing ankle pain compared with football and hockey players.

CONCLUSIONS

The highest percentage of knee 81.9% and ankle 62.3% pain, as well as the greatest risk of pain, was found among floorball players. Hockey players had the highest prevalence (97.2%) and risk of developing hip pain.

Prevention of shoulder injuries in volleyball players: The usefulness and efficiency of a warm-up routine

OBJECTIVES

The objective of this study was to assess the efficiency of a warm-up routine focused on shoulder injury prevention in volleyball players.

DESIGN

Prospective study.

SETTING

University.

PARTICIPANTS

Eight recreational volleyball teams (44 males, 49 females) were included in the study and assigned to two different groups (prevention or control) in a blinded way. In the prevention group, the players had to perform specific exercises at the beginning of each training session twice a week.

MAIN OUTCOME MEASURES

Injuries were recorded monthly in both groups with an online questionnaire.

RESULTS

A significant decrease in the total number of injuries as well as in the severity of the injuries was observed in the prevention group in comparison to the control group (p = 0.0001-0.013). For the shoulder, a decrease in injury incidence was also observed in the prevention group. This decrease reached significance in male players (p = 0.045).

CONCLUSIONS

The program appears to be efficient to reduce the risk of shoulder injuries in recreational volleyball players. Adjustments in the duration and in the contents of the program will have to be made to further improve compliance and better meet the requirements of both players and trainers.

Injuries and complaints in the Brazilian national volleyball male team: a case study

BACKGROUND

The literature reports a vast amount of epidemiological information on injuries in volleyball athletes. However, little is known about the incidence of injuries in elite athletes of international level participating in major competitions, such as world championships and Olympic games. The objective of the study was to analyse the incidence of injuries in elite professional volleyball athletes, and the prevalence of complaints reported by athletes.

METHODS

This is a case study in which data were collected between April 2018 and August 2021. All the athletes called to play for the Brazilian national male volleyball team during the analysis period participated. From the athletes' medical records, the occurrence of injuries (injurious events that lead to a time off from activities) and complaints (discomforts that did not lead to a time off from activities) were analysed. Frequency data were used to calculate incidence, prevalence and ratios.

RESULTS

From 41 athletes who played for the team during the analysed period, 12 athletes had 28 injuries and 38 athletes reported 402 complaints. For injuries, an incidence of seven injuries/1,000 h of competition and two injuries/1,000 h of training was observed. The average recovery time of the athletes was 10 days. The regions with the highest prevalence of injuries were the knee (111/1,000 athletes) and ankle (69/1,000 athletes). For complaints, 402 complaints required 1,085 treatment sessions, with the regions with the highest prevalence of complaints being the knee (261/1,000 complaints) followed by the shoulders (236/1,000 complaints). Athletes aged above 23 years and those playing as middle blockers and outside hitters presented a higher prevalence of injuries and complaints.

CONCLUSIONS

Almost one-third of the athletes had injuries and almost all athletes reported complaints during the study period. Injuries and complaints were more prevalent in the knees. Complaints caused a high demand for the healthcare team. To manage risk of injuries for overload, specific injury prevention strategies are needed and should be included as an essential component of the training plan for elite volleyball players.

Effect of an injury prevention program on the lower limb stability in young volleyball players

BACKGROUND

Volleyball players have a high risk of injury in the lower limbs as a consequence of the specific characteristics of the sport, such as repetitive jumps and falls. The objective of the present study was to evaluate the effects of a multidisciplinary injury prevention program on lower limb stability in young volleyball players.

METHODS

The experimental design was a non-randomized controlled trial. All the measurements were performed in a standardized room in a sports center. Twenty-six young male volleyball players (mean age: 15.39±1.16 years), divided into experimental (N.=15) and control groups (N.=11) participated in this study. The experimental group performed an 8-week prevention program including lower limb strength and plyometric training, and joint and core stability. The Y-Balance and force platform landing tests were carried out as the pre- and post-tests.

RESULTS

The main outcome measures were the injuries history, distance and difference reached in anterior, post-lateral and post-medial axis of the Y-Balance test, and the force produced on the z, x, and y axis after landing. Differences were found between groups and measurements in all the variables of the Y-Balance test, except in the frontal axis for the dominant leg and for the differences between legs (P=0.039-0.001); and in the ground reaction forces (z axis) (P=0.040), the x axis (P=0.014) and the dynamic postural stability index (P=0.025) of the lateral jump with the non-dominant leg.

CONCLUSIONS

An 8-week prevention program seems to improve the lower limb stability in young volleyball players.

Prevalence and Factors Associated With Injuries in Elite Spanish Volleyball

CONTEXT

Prevalence studies have been carried out widely on elite volleyball players. However, the extent to which specific prevention strategies are used and the influence of the sport equipment on the occurrence of injuries have been sparsely investigated.

OBJECTIVE

To describe the prevalence of injuries sustained during 1 season in elite Spanish volleyball leagues and to investigate the association of injuries with factors such as player court position, injury mechanism, type of shoes used when playing, or participation in prevention activities.

DESIGN

Descriptive cross-sectional epidemiology study: observational study.

SETTING

European elite professional volleyball.

PARTICIPANTS

Professional volleyball players from the elite Spanish volleyball league.

MAIN OUTCOME MEASURES

A self-report questionnaire assessed the presence of injury during a volleyball season. Questions included the type of injury, its anatomic location, participation in prevention strategies, shoe type, the injury mechanism, the season period, the period of leave, and the treatment received.

RESULTS

In total, 490 players (71.2% response rate) completed and returned the questionnaire. The injury prevalence was 66.9%, and the average of injuries per player was 0.94 (0.85) (range: 0-4). Most Spanish elite volleyball players participated in prevention programs during the season (90.3%) and played volleyball with low-top shoes (83.6%), but these factors were not associated with the prevalence of injuries (P > .05). The anatomic regions with the most injuries were the ankle, knee, and shoulder; the most common types of injury were sprains, tendinopathies, and strains, usually occurring during blocking and attack actions during the in-season period.

CONCLUSIONS

Despite most elite volleyball players participating in prevention programs, the results reveal a high injury prevalence. Further prospective research on the effectiveness of prevention strategies in elite volleyball is needed.

Landing-related ankle injuries do not occur in plantarflexion as once thought: a systematic video analysis of ankle injuries in world-class volleyball

Background

Ankle injuries are prevalent in elite volleyball and suggested to result from player contact at the net. Traditionally, ankle sprains are thought to happen in a plantarflexed position, but case studies suggest plantarflexion may not be involved.

Aim

Describe the injury situations and mechanisms of ankle injuries in world-class volleyball based on systematic video analysis of injuries reported through the Fédération Internationale de Volleyball (FIVB) Injury Surveillance System.

Methods

Videos of 24 injuries from major FIVB tournaments were included for analysis (14 men, 10 women). Five analysts reviewed the videos to determine specific situations and mechanisms leading to injuries.

Results

The majority of injuries occurred during two volleyball situations, blocking (n=15) and attacking (n=6). Injuries to blockers were the result of landing on an opponent (n=11) or teammate (n=4). Attacking injuries most frequently occurred when a back-row player landed on a front-row teammate (n=4 of 6). When landing on an opponent under the net, the attacker landed into the opponent’s court in 11 of 12 situations but without violating the centre line rule. Injuries mostly resulted from rapid inversion without any substantial plantarflexion.

Conclusions

The majority of injuries occur while blocking, often landing on an opponent. The attacker is overwhelmingly to blame for injuries at the net secondary to crossing the centre line. Injuries while attacking often result from a back-row player landing on a front-row teammate. Landing-related injuries mostly result from rapid inversion with the absence of plantarflexion.

Injury risk is low among world-class volleyball players: 4-year data from the FIVB Injury Surveillance System

Background

Little is known about the rate and pattern of injuries in international volleyball competition.

Objective

To describe the risk and pattern of injuries among world-class players based on data from the The International Volleyball Federation (FIVB) Injury Surveillance System (ISS) (junior and senior, male and female).

Methods

The FIVB ISS is based on prospective registration of injuries by team medical staff during all major FIVB tournaments (World Championships, World Cup, World Grand Prix, World League, Olympic Games). This paper is based on 4-year data (September 2010 to November 2014) obtained through the FIVB ISS during 32 major FIVB events (23 senior and 9 junior).

Results

The incidence of time-loss injuries during match play was 3.8/1000 player hours (95% CI 3.0 to 4.5); this was greater for senior players than for junior players (relative risk: 2.04, 1.29 to 3.21), while there was no difference between males and females (1.04, 0.70 to 1.55). Across all age and sex groups, the ankle was the most commonly injured body part (25.9%), followed by the knee (15.2%), fingers/thumb (10.7%) and lower back (8.9%). Injury incidence was greater for centre players and lower for liberos than for other player functions; injury patterns also differed between player functions.

Conclusions

Volleyball is a very safe sport, even at the highest levels of play. Preventive measures should focus on acute ankle and finger sprains, and overuse injuries in the knee, lower back and shoulder.

The incidence and prevalence of ankle sprain injury: a systematic review and meta-analysis of prospective epidemiological studies

BACKGROUND

Ankle sprain is one of the most common musculoskeletal injuries, yet a contemporary review and meta-analysis of prospective epidemiological studies investigating ankle sprain does not exist.

OBJECTIVE

Our aim is to provide an up-to-date account of the incidence rate and prevalence period of ankle sprain injury unlimited by timeframe or context activity.

METHODS

We conducted a systematic review and meta-analyses of English articles using relevant computerised databases. Search terms included Medical Search Headings for the ankle joint, injury and epidemiology. The following inclusion criteria were used: the study must report epidemiology findings of injuries sustained in an observed sample; the study must report ankle sprain injury with either incidence rate or prevalence period among the surveyed sample, or provide sufficient data from which these figures could be calculated; the study design must be prospective. Independent extraction of articles was performed by two authors using pre-determined data fields.

RESULTS

One-hundred and eighty-one prospective epidemiology studies from 144 separate papers were included. The average rating of all the included studies was 6.67/11, based on an adapted version of the STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) guidelines for rating observational studies. 116 studies were considered high quality and 65 were considered low quality. The main findings of the meta-analysis demonstrated a higher incidence of ankle sprain in females compared with males (13.6 vs 6.94 per 1,000 exposures), in children compared with adolescents (2.85 vs 1.94 per 1,000 exposures) and adolescents compared with adults (1.94 vs 0.72 per 1,000 exposures). The sport category with the highest incidence of ankle sprain was indoor/court sports, with a cumulative incidence rate of 7 per 1,000 exposures or 1.37 per 1,000 athlete exposures and 4.9 per 1,000 h. Low-quality studies tended to underestimate the incidence of ankle sprain when compared with high-quality studies (0.54 vs 11.55 per 1,000 exposures). Ankle sprain prevalence period estimates were similar across sub-groups. Lateral ankle sprain was the most commonly observed type of ankle sprain.

CONCLUSIONS

Females were at a higher risk of sustaining an ankle sprain compared with males and children compared with adolescents and adults, with indoor and court sports the highest risk activity. Studies at a greater risk of bias were more likely to underestimate the risk of ankle sprain. Participants were at a significantly higher risk of sustaining a lateral ankle sprain compared with syndesmotic and medial ankle sprains.

Shoulder pain in Iranian elite athletes: the prevalence and risk factors

OBJECTIVE

Shoulder sports injuries are relatively common in athletes who perform highly repetitive motions. The purposes of this study were to determine the prevalence of and risk factors for shoulder injuries and to analyze how individual and other sport characteristics contribute to the risk of shoulder injuries among 6 overhead sports, those being swimming, rowing, wrestling, basketball, volleyball, and handball.

METHODS

A cross-sectional study was carried out on 613 Iranian overhead sports athletes in different collegiate sport fields. Data were collected using different questionnaires. A structured questionnaire including demographics, sport characteristics, and also prevalence and risk factors of shoulder pain was used. Visual analogue scale and Disability of the Arm, Shoulder, and Hand questionnaires were used to determine the pain intensity and functional disability, respectively.

RESULTS

Point, last 6-month, last year, and lifetime prevalences of shoulder pain were 21.4%, 29%, 38.8%, and 41.6%, respectively. The highest point prevalence was related to the rowing athletes with 31.9% and the lowest for swimming athletes (12.3%). Sex, body mass index, sport level, days of practice per week, and satisfaction with income were found to be significantly correlated with the prevalence of shoulder pain (P < .05 in all instances). For those with shoulder pain, the mean pain intensity and functional disability were 53.8 mm and 15.46%, respectively.

CONCLUSIONS

The prevalence of shoulder pain in athletes with highly repetitive overhead motions seems to be high.
